RUFFLING AND SEWINGMACHINE.

Application filed April-8, 1922.` SerialNO., 550,849.

.'. Illinois, have invented certain new and useful Improvements in Rulfling and Sewing Machines, of which thefollowing is adescription, reference being had to the accompanying drawing and to the figures ofreference marked thereon.

The invention relates to new and useful improvements in a ruiiiing and sewing niachine 'Of the type shown in the patent granted to Russell T'. "Woodward, August i 5, 1902, and numbered 706,484. Said machine discloses a rufliing mechanism mounted beneath the work support and actuated from the main shaft beneath the said work support, and wherein the ruling blade engages the underface of the upper fabric section for laying-the same 1n gathers or ruftles subsequent to the same-.being stitched It 1s often` desirable in sucha type of machine to ruflie to an under section of fabric.

a portion of a fabric section and to stitch that is, without any ruffles therein.

An object of the invention is to provide.'

means whereby a rufliingblade ofthe above type of machine may be moved at will laterally of the line of feed to inoperative position, so that the fabric sections mayy be stitched plain and without rufling although y the rufHing blade .continues to A still further object of the invention is to provide amac-hine of the above type with a guide for the upper strip of fabric which is also moved laterally with the 'ruffling cblade and thereby withdrawn from its engagement with the fabric section.

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed In the drawings which show by wayfof illustration one embodiment vof the invention- Figure lis a frontview of ay portion 0f aV machine embodying my invention;

I Said segment ylever' 12 iscarried by a stubshaft 14%journaledv in said lbracket 13. Thezs'egment lever 12v is oscillated in its supporting bearing byithe eccentricv strap l5 which co-'oper'ates with the eccentricon the main shafty'as: fuillyfset forth in the Voodward' patent. frisfthe main shaft rotates it-willf'osci-llatethe segr ment lever 1,2.andv the segment 'leverl2 will in turn impart an oscillation -tovthefroclrf` frame 10 and the rook framev 1'() 'wi'll through the link 91 oscillate thearmvS and the shaft 7 with 'which itis'rigidlyuconnected.

v Mountedon the shaft 8 and-.1 extending i upwardly therefrom isa bracket member 16` carrying two spaced'rarms landv 18. VAt

the upper endof eacharmf171andfl8`fthere f is a sleeve.

Mountedinfsaid-` sleeve fissai y i shaft orusupportlQ which.l isf-provided `withf a rib 20 adapted to engageda recessl21rin each'sleeve. This permits` the shaft V19 Itov move endwise, but said shaft :is he'ldffrom" 'rotating or oscillatingin thesleeves 17 and 18. Freely mountedon the endfof the; shaft is an arm. 22. A -spring23 iss'e'cured tothe shaft 19 at oneendand thewarm 22 at its other end, and is coiled aboutthe'shaft sol as tonormallyturnv the arm [on.theislraftA in'a clockwisedir'ection-as viewed in-.Fig..l3`.

vFixed to this arm 22 fisthe ruiiiingf'blade24.

Said rulfiing blade extends forward toward Cil needle which is shown at in Fig. 3 of the drawings. The feed dog of the machine is indicated at 26 and the presser foot at 2T. The lower section of fabric is indicatedat F and the section being ruii'ied is indicated at F. The presser foot has an upturned toe 28 of the usual construction and directly in front of said upturned toe is a guide 29 for the upper strip of fabric. Said guide 29 consists of a lower guiding plate 30 having its eXtreme upper end turned down at 31, and an upper plate 32. The lower plate is relatively short, as clearly shown in Fig. 3, so that the upper plate extends beyond the lower plate and to a point adjacent the upturned toe 28. rlhe rufi'ling blade 22 is turned by its sprii'ig` upwardly into contact with the fabric section passing between the plates 30 and 32 and will bear against the upper plate 32 and then against the underface of the upturned toe 2S as it moves forward. rlhe plates oO and 32 are provided with slots 33 33 and screws passing through these slots secure the plates to a supporting shan i 34. This supporting shank 34 is carried by a plate 35 mounted on the upper face of the work support 2. Said plate 35 is provided with a longitudinal slot 36. Overlying said slot isa spring steel plate 37 and screws 38--38 pass down through said spring plate and the slot 3G and are threaded vinto the work support. The plate 35 is therefore capable of being moved endwise from the full line position shown in Fig. 2 to the dotted line position shown therein. lllhen moved to the dotted line position the plates 30 and 32 will be withdrawn fiom the strip of fabric F so that said strip of fabric may be laid flat on the lower strip of fabric and stitched thereto without ruftling.

In order that the ruftling blade may be simultaneously moved laterally with the guide plates 30 and 32, I have secured to saidY plate 3G a bracket 39. Said bracket has slots 40-40 through which screws -5O passl for adjustably securing the bracket to the plate 36. Said bracket 39 has an outwardly projecting curved arm 41. Mounted on the shaft or support 19 is a collar 42. Said collarl is Fixed to said support 19. Said collar is provided with a segmental groove 43 which conforms to thev shape of the arm 41. The arm 41 is curved about the axis of the shaft/7 asa center. As a -result tle bracket 16 carrying the ruifling blade may rock with the shaftv 7 and the collar will slide back and forth freely on the arm 41. Any sidewise movement of the arm 41 however, will move the shaft 19 endwise in the supporting sleeves 17 and 18.

Then the parts are in full line position shown in Fig. 2, strips of fabric may be led to the stitching mechanism, the one beneath theruftiing blade and the otherabove said blade. The lower fabric` section F will lie plain and without any gat-hers therein because the ruftiing blade is spring pressed upward and will not contact with said lower fabric section. The upper fabric section F is led between the guide plates 30 and 32 and will be engaged by the ruiiiiiig blade and laid in gathers or rufiies which will be entered by the needle and these ruffies will be stitched to the 'lower fabric section. lVhen a point is reached in the forming of an article where it is desired to suspend the ruffling and stitch the two fabric sections together plain and unrutlled, then the operator by pushing on the arm 41 or any other suitable place, may move the shaft 19 endwise and simultaneous with the eiidwise movement of the shaft the plate 36 will be moved longitudinally and this will carry both the rufilingblade and the guiding plates 30 and 32 to the dotted line position shown in Fig. 2. The ruftling blade may continue its oscillations back and forth but it is new out of range of the fabric sections and is, therefore, ineffective.

lt will, therefore, be seen that l have provided very simple means whereby at the will of the operator a ruliiing mechanism and fabric guiding mechanism may be rendered ineffective by a movement of the. saine laterally to a position where it will not engage and operate upon the fabric sections being stitched.

lt is obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claims.

Having thus described my invention, what Iclaim as new and desire to secure by Let-- ters Patent, is:

1. A sewiru.T and ruftling machine comprising a weil; support, a stitching mechanism, feeding mechanism and a ruiiing mechanism, said ruftiing mechanism including a rock shaft mounted beneath the work support, an arm projecting upward 'therefrom and carrying a rufliing blade overhanging the work support, a fabric guide co-operating with the rutlling blade, and means whereby said fabric guide and ruflling blade may be simultaneously moved 'in a straight line transversely of the line of feed to ineffective position.

2. A sewing and ru'liling machine comprising a work support, a stitching mechanism,

.feeding mechanism and a ruftling mechanism, said ruffling mechanism including a rock shaft mounted beneath the work support, an arm carried thereby and projecting' above the work support, a ruffling blade carried by said arm, a spring normally pressing said rufiimg blade upwardly, a lfabric guide with which said ruitling blade co-operates,

whereby the upper section of fabric may be ruffled, and means whereby said rufling blade and fabric guide may be simultaneously moved in a straight line transversely of the line of feed to ineffective position.

3. A sewing and rufl'ling machine comprising a work support, a stitching mechanism, feeding mechanism and a ruftling Amechanism, said ruiiling mechanism including a rock shaft mounted beneath the work sup-` port, arms rigidly mounted on the rock shaftv and projecting above the work support, a sleeve at the upper end of each arm, a shaft mounted in said sleeves and capable of endwise movement only therein, a ruftling blade freely carried by said shaft, a spring normally moving said ruiiing blade upwardly away from the work support, a fabric guide co-operating with the rufiling blade, whereby the upper section of fabric may be ruffled, and means for simultaneously moving the fabric guide and the shaft carrying the rutiling blade endwise transversely of the line of feed to ineffective position.

l. A sewing and ruffling machine comprising a work support, a .stitching mechanism, feeding mechanism and a ruiing mechaiiism, said rufliing mechanism including a rock shaft mounted beneath the work support, arms projecting upwardly `above the work support and each having a sleeve at the outer end, a shaft mounted in said sleeve for endwise movement only therein, a rutling blade freely mounted on the shaft, a spring for turning the ruftiing blade upwardly away from the work support, a fabric guide cooperating with said ruflling blade, va plate carrying' said fabric guide, means for sup,

porting said plate, whereby the same may be moved longitudinally on the work support, and in a direction parallel with the movement of the shaft carrying the rui'iing blade, and means whereby the endwise movement of the shaft will cause a longitudinal movement of said plate and the simultaneous movement of the ruiiling blade and the fabric guide to ineffective or effective position.L Y i l 5. A sewing and rufHing machinecomprising a work support, a stitching mechanism,

feeding mechanism, and a ruffling `mecha nism, said rufi'ling mechanism including a rock shaft mounted beneath the work sup-` port, arms projecting upwardly above the work support and each having a sleeve at the outerrend,a shaft` mounted in said sleeve for endwise movement only therein, a rufling -V v a sleeve fixed to said shaft and having' a recess engaging said arm, whereby said shaft `may be moved back and forth vtoward and from said plate, and whereby endwise movement of the shaft will move said Aplate longitudinally.

In testimony whereof, I afHX my signature.
